In this experiment we will use this special box. On one side we will have cold water and on the other side we will have hot rocks.
We will hold incense which will produce smoke above the cold water side.
Predict what will happen to the smoke.

Matter and Its Interactions
Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
Clarification Statement: Emphasis is on qualitative molecular-level models of solids, liquids, and gases to show that adding or removing thermal energy increases or decreases kinetic energy of the particles until a change of state occurs. Examples of models could include drawings and diagrams. Examples of particles could include molecules or inert atoms. Examples of pure substances could include water, carbon dioxide, and helium.

Energy
Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
Clarification Statement: Examples of empirical evidence used in arguments could include an inventory or other represen- tation of the energy before and after the transfer in the form of temperature changes or motion of object. [Assessment Boundary: Assessment does not include calculations of energy.]
